FIRST LOOK: John Mayer Jilts a Bride in 'Half of My Heart'

The notorious serial dater, who back in December said his love life was on hiatus, seems to be back to his playboy ways – at least on the small screen.

PEOPLE has the exclusive premiere of the singer’s “Half of My Heart” video, where a tux-clad Mayer, 32, sings and strums about not being able to “stop loving you with half of my heart” after apparently leaving his bride at the altar.

Taylor Swift fans who hoped to see the country singer in the video are out of luck. Swift, who recorded the song with Mayer for his 2009 album Battle Studies, never makes an appearance. – Eunice Oh
